I have been looking into how to evolve my marill into azumarill but
I have not found a way to do this. Will it evolve on its own
eventually or is there a item I am suppose to do. Please Help.
Marill evolves into Azumarill at level 18. I found one in your
boxes and fed it a berry to level it up, so it’s an Azumarill now!
Serebii is a great resource for seeing how Pokemon evolve, mainly
for level-up evolutions since other special evolutions are
different on PH sometimes.
Edit: Azurill to Marill is the one that requires a soothe bell, not
Marill to Azumarill :)
